s designed for long serv ice l ife ductile iron body maintains the anti - corrosive properties of cast iron while achieving a yield strength comparable to carbon steel . ductile iron also offers higher pressure / temperature ratings than cast iron . carbon and stainless steel units are also available upon request . s minimal head loss head loss is minimized by providing a large cross - sectional area which exceeds that of the adjacent pipeline . additionally , the spring - loaded , center guided disc is designed with very low cracking pressure which reduces the amount of energy required to open the valve . s qui ck closure to reduce water hammer silent shut - off is achieved via the fully automatic , spring assisted disc that closes near zero flow velocity . the lightweight , center guided disc design creates a positive shutoff prior to flow reversal and helps to keep slamming and surges to a minimum . s bronze metal - to - metal seats precision machined sealing surfaces allow the fv 50 - di to maintain a tight seal that meets or exceeds api 598 leakage requirements . resilient seats are also available to provide bubble tight seals . s numerous screen opt ions the standard screen construction material is type - 304 stainless steel . in addition , a wide variety perforations , meshes , and materials are readily available . screens can be b asket shaped or cone shaped .

1. The bolting pattern for Cast Iron ASME Class 125 and Ductile Iron ASME Class 150 are identical thus they are interchangeable. 2. The above listed temperatures are theoretical and may vary during actual operating conditions. 3. Longterm use at maximum temperature is not recommended for optimal performance. Longterm use at maximum temperature will result in performance degradation.
general application : a foot valve is a special type of check valve that has a built - in strainer . it is installed at the intake side of a suction pipe and pump . its purpose is to prevent the loss of prime when the liquid source ( wet well ) is lower than the pump . prime is defined as the charge of liquid required to begin pumping action and priming is the process of filling the pump and suction pipe with liquid . the check valve part of the foot valve opens when the pump starts to allow liquid to enter the suction pipe and pump . when the pump stops the check valves closes and prevents the liquid from emptying . thus the foot valve eliminates the need to prime the pump each time it is started . the strainer component of the foot valve helps to remove unwanted debris from the liquid that may cause damage to the pump .
The above data represents common market and service applications. No representation or guarantee, expressed or implied, is given due to the numerous variations of concentrations, temperatures and flow conditions that may occur during actual service.
